well some say there is a large possibility of HRE(holy roman empire) grew up to be Germany

the only proof i could give is

the "boun san valentino" web comic
-in the end of the web comic, Germany's mind became flooded with emotion and a memory of Chibitalia was shown from his point of view.
also
some physical resemblance
-when Germany`s hair ids not slicked back

it is also hinted

he survived the war but gained amnesia.......

hats the only info i have...

so what do guys think.....?( sorry i pressed post twice so there are two post please reply on the one above this one ok)
sorry, sumimasen,
